Pressure washer pump unloaders control direction of water flow exiting the pump. Therefore, a pressure washer pump unloader works as a safety device, making it a very important part of a working 5000psi + pressure washer pump. Water Cannon carries the web's largest variety of 5000psi + pressure washer pump unloaders from the industry's most trusted names: Annovi Reverberi, PA, General Pump, Cat Pump, Suttner, Mecline and more.
Water Cannon recommends using a safety relief device in conjunction with a positive displacement triplex plunger pump or equal.
